【django】 接收所有文件，前端展示文件（包括视频，文件，图片）ajax请求
如果是后台上传文件: setting配置： STATIC_URL = '/static/' STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'static'), os.path.join(BASE_DIR, "media"), ] # Django用户上传的都叫media文件 MEDIA_URL = "/media/" # media配置，用户上传的文件都默认放在这个文件夹下 MEDIA_ROOT = os.path.join(BASE_DIR, "media") model的配置： img = models.FileField(upload_to="img/",verbose_name="图片")
接收任何文件的前端代码： <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <form method="post" action="/upload/" enctype="multipart/form-data" target="ifm1"> <input type="file" name="file" id="file"/> <input type="button" value="提交" onclick="upload()"/> </form> <br> <br> <br> <br> <div>显示图片 <img id="images"> </div> <br> <br> <br> <br> <div>显示路径 <a href="" id="imagess">链接</a> </div> </div> <br> <br> <br> <br> <div> {# href="/static/img/TC代码.txt" #} <a id="up"> 下载文件</a> </div> <script src="https://cdn.staticfile.org/jquery/1.10.2/jquery.min.js"></script> <script> function upload() { var formData = new FormData(); var file = document.getElementById('file').files[0]; formData.append("file", file); $.ajax({ url: "upload/", type: "post", data: formData, dataType: "json", cache: false, //上传文件无需缓存 processData: false,//用于对data参数进行序列化处理 这里必须false contentType: false, //必须*/ success: function (data) { console.log("22", data); $("#images").attr("src", data.image) $("#imagess").attr("href", data.image) } }); } $("#up").on("click", function () { $.ajax({ url: "http://127.0.0.1:8000/down/", type: "get", data: {}, success: function (data) { var $a = $('<a></a>'); $a.attr("href", "http://127.0.0.1:8000/down/"); $("body").append($a); $a[0].click(); $a.remove(); } }) }); </script> </body> </html>
增加任何文件的后端接口代码： from rest_framework.views import APIView from django.shortcuts import render, redirect, HttpResponse from dal import models from django.http import JsonResponse class ImageShow(APIView): def post(self, request): name = str(request.data.get("name")) message = {} img_url = "/static/img/{}".format(name) obj = models.Car.objects.filter(img_url=img_url).first() if obj : message['code'] = 200 message['message'] = img_url # 返还路径 return JsonResponse(message)
下载文件后端： from django.utils.http import urlquote from rest_framework.views import APIView from django.shortcuts import render, redirect, HttpResponse from dal import models from django.http import JsonResponse, FileResponse, StreamingHttpResponse class fileShow(APIView): def get(self, request): message = {} file = open('media/img/TC代码.txt','rb') # 字符串替换成文件 print("file",file.name) # file_names = file.name.split('/')[-1] # print("file_names",file_names) response = FileResponse(file) response['Content-Type'] = 'application/octet-stream' response['Content-Disposition'] = "attachment;filename={}".format(urlquote("TC代码.txt")) # 字符串替换成下载文件 print(response) return response
